Antenna frame, antenna structure, and watch type wave clock having the antenna structure

Abstract

An antenna frame that can suppress shock given to an antenna and position the antenna with controlling increase in size to a minimum, an antenna structure, and a wave clock having the antenna structure are provided. An antenna frame of an antenna structure of a wave clock comprises a frame made of a nonconductive material for receiving and fixing an antenna having an elongated and rod-like, magnetic core and a winding wire wound on the center in a longitudinal direction of the magnetic core. The frame has a recess including a recess portion for receiving a winding portion of the antenna and recess portions for receiving two ends of the magnetic core at both sides of the portion, and end mountings to be mounted on a base at the two ends. When the antenna is received in the recess, ends of the magnetic core are positioned with respect to the portions. The end mountings are mounted on the base in a manner of being contacted to a mounting surface at base side surfaces.

1. An antenna frame comprising:
 a nonconductive material for receiving and fixing an antenna having an elongated and rod-like, magnetic core and a winding wire wound on the center in a longitudinal direction of the core; 
 a recess including a receiving recess portion for winding part for receiving a winding portion of the antenna and receiving recess portions for magnetic-core ends for receiving two ends of the magnetic core at both sides of the receiving recess portion for winding part, and having end mountings to be mounted on a base at the two ends, 
 wherein when the antenna is received in the recess, the ends of the magnetic core of the antenna are positioned with respect to the receiving recess portions for magnetic-core ends, 
 and wherein the end mountings are mounted on the base in a manner of being contacted to a mounting surface of the base at base side surfaces having openings of the recess. 
 
   
   
     2. An antenna structure comprising:
 an antenna having an elongated and rod-like, magnetic core and a winding wire wound on the center in a longitudinal direction of the core and an antenna frame comprising a nonconductive material, wherein 
 the antenna frame has a recess including a receiving recess portion for winding part for receiving a winding portion of the antenna and receiving recess portions for magnetic-core ends for receiving two ends of the magnetic core at both sides of the receiving recess portion for winding part, and has end mountings to be mounted on a base at the two ends, and 
 the antenna frame is configured such that when the antenna is received in the recess, the ends of the magnetic core of the antenna are positioned with respect to the receiving recess portions for magnetic-core ends, and 
 the antenna frame is configured such that the end mountings are mounted on the base in a manner of being contacted to a mounting surface of the base at base side surfaces having openings of the recess. 
 
   
   
     3. An antenna structure according to  claim 2 , wherein the magnetic core is curved arcuately, and the antenna frame has an outer circumferential wall for covering an outer circumference side of the magnetic core. 
   
   
     4. An antenna structure according to  claim 2 , wherein the antenna frame has a projection on a wall situated at a side opposite to the base side surface. 
   
   
     5. A watch type wave clock having the antenna structure according to  claim 2 .
